I have zero experience with workstation PCs but one of my coworkers who is a PCB designer just got a new work station with 2 30" Dell monitors. Their native resolution is 2560x1600 and her video card is a NVidia Quadro FX3450/4000 (dunno which but thats what the driver identifies it as). The OS is Windows XP x64. I think the PCs were 'designed' and ordered by a guy who wasn't the most informed about computers and just wanted bigger monitors, but he doesn't work in the dept anymore.

She is only able to run one monitor at up 1920x1200 while the other is at 2560x1600, but not both at native res. I don't know if this card can't handle the resolution needs, there is a driver issue (she was running 72.13 and is now running 268.xx [the newest driver]), or a problem with Windows XP.

If you really wanted to find out, go to the properties of the display adapter in device manager, click on the Details tab, make sure you're looking at Device Instance Id, and take the VEN_XXXX and DEV_YYYY (where XXXX and YYYY are hexadecimal numbers) over to some place like this and search (preferrably by device ID, using the vendor ID to confirm a match).

If she disables one of the monitors, can she crank the single monitor left up to its native res?

If you can find out exactly which card she's got (e.g. using the PCI device ID like I mentioned above), you can always look up the specs/limits of the card, but it does indeed sound like you're trying to output more than what that card can handle.
